BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 621,759, dated March21, 1899.

Application filed December 27, 1898. Serial No. 700,314. (No model.)

used on a bicycle or like vehicle for sounding.

a warning or alarm; and the object of my invention is to provide abicycle-bell with means whereby the thumb-lever or push-but- -ton usedfor operating the mechanism may changed as may be desired to accommodatethe bell to varying conditions of use in attachment to different parts.

To this end my invention consists in the device as awhole, in thecombination of parts, and in the details and their combination, ashereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a view in side elevation of abicycle-bell embodying my invention. Fig. 2 is a detail top or plan viewof the same with the gong removed. Fig. 3 is a detail view, in centralvertical section, through the base-piece and clamp with the strikingmechanism and gong removed. Fig. 4 is a detail view showing in elevationthe gong-post, the thimble, and one section of the clamp separated. Fig.5 shows detail end views of these parts.

In the accompanying drawings the letter a denotes the clamp as a whole;I), the bell-base; c, the thumb-lever, and d the gong of a bicyclebell.The clamp, as to its clamping features, may be of any desiredconstruction, a form in common use at the present time having beenselected for the purpose of illustrating herein my improvement. Thisclamp has a clamp-base 6, through which is a hole e. In the preferredform of the invention this hole has tapering walls, as shown in thedrawings, being smaller at that end next to the bellbase than at theopposite end.

A thimble f is formed, as to its outer surface, to fit the hole e at ornear its inner end, and by inner end I mean that end next to thebell-base, this fit being such as to allow free turning movement of thethimble within the hole in the clamp-base. The end wall f of thisthimble has an opening f of such shape in cross-section as to prevent apost 9 from turning therein, the opening inthe form shown being oblong.The thimble when socured in place formsv what may betermed a hub for thebell-base. The post 9 extends through the bell-base and is secured inthe opening f preferably as by means of riveting. The opening in thebell-base is made to conform to the shape of the end of the post, andthat part of the post extending through the bell-base and clamp-base isreduced, as shown in the drawings. This means of securing the post inposition is the ordinary form now employed in bells of this class.

A set-screw h extends through the wall of the clamp-base e, its endseating against the outer surface of the thimble. The end of thisset-screw is preferably tapered, such form v v herein.

Bell-striking mechanism of any desired form may be used in connectionwith the device, mechanism employing a thumb-lever, push-button, or likeoperating means, however, having special advantages when used inconnection with my improvement.

Although a set-screw operated by a screwdriver is shown herein as aready means for adjusting the bell-base at the same time and with thesame tool as is employed to secure the clamp, it is to be understoodthat such means for clamping the clamp-base to the thimble are notessential to the invention.

Iclaim as my invention I 1. In combination in abicycle-bell, a clamp,a'bell-base, a hub rigidly secured to one of said parts and adapted tobe located in an ing, means for clamping the hub against movement in theopening, bell-striking mechanism with meansfor operating the same, and agong supported in operative relation to the bell-striking mechanism.

In combination in a bicycle-bell, aclamp, a bell-base, a tapered hubrigidly secured to one of said parts and adapted to be located in atapered opening in the opposite part, means for clamping the hub againstmovement in the opening, bell-striking mechan ism With means foroperating the same, and a gong supported in operative relation to thebell-striking mechanism.

4. In combination in abicycle-bell, a clamp having a clamp-base with atapered opening therein, a bell-base having a hub rigidly securedthereto and adapted to fit Within said opening, means for clamping thehub against movement therein, bell-striking mechanism with means foroperating the same, and a gongsupported in operative relation to thebell-striking mechanism.

5. In combination in a bicycle-bell,a clamp, a bell-base, a tapered hubon one of said part-s adapted to be located in'a tapered opening inthe'opposite part, a'set-screw seating against the hub, bell-strikingmechanism with means for operating the same, and a gong supported inoperative relation to the bell-striking mechanism.

. 6. In combination in a bicycle-bell, a clamp having an opening, abell-base, a thimble rigidly secured against rotation to the bellbaseand fitting the opening in the clamp, means for clamping the thimbleagainst movement in said opening, bell-striking mechanism With means foroperating the same, and a gon'g supported in opeartive relation to thebell-striking mechanism.

7. In combination ina bicycle-bell, a clamp having a tapered opening, abell-base, a taered thimble rigidly secured against rotation to thebell-base and fitting the opening in the clamp, means for clamping thethimble against movement in said opening, bell-striking mechanism withmeans for operating the same, and a gong supported in operative relationto the bell-striking mechanism.

8. In abicycle-bell, in combination,a clamp having an opening, abell-base, a thimble fitting the opening in the clamp, a gong-postextending throughthe bell-base and thimble and rigidly securing themtogether against relative rotation, means for clamping the thimbleagainst movement in said opening, bell-striking mechanism with means foroperating the same, and a gong supported in operative relation to thebell-striking mechanism.
